Question

What’s the error for the mathematical equation

Answer 1

The error is either the line graph or the equation is wrong. -17.4 > x means that -17.4 is the largest possible number and anything under it would be a solution. However, the number line shows that everything above -17.4 is a solution, so therefore the equation would have to be -17.4<x instead.

Answer 2

-17.4 > x means that any answer less than -17.4 makes the inequality true. Thus, the person has the arrow going the wrong way as it should be pointing left to the numbers less than -17.4
